TitleOptic nerve metastases from rectal adenocarcinoma – a case report
PurposeWe present a rare case of a metastatic optic nerve disease due to histologically proven colorectal adenocarcinoma.
MethodsA 49-year-old man, with a known history of rectal adenocarcinoma, presented with progressive loss of vision in his left eye. On presentation, his vision was 6/36 in the right eye and counting fingers in the left eye.
ResultsFundus examination showed a left globally swollen optic nerve with a few flame haemorrhages. A gadolinium enhanced MRI scan was performed and demonstrated an abnormal thickening of the anterior and mid-section of the optic nerve with high signal on STIR and post gadolinium enhancement. An optic nerve biopsy was performed and histology confirmed the presence of epithelial adenocarcinoma compatible with metastasis of gut origin.
ConclusionThe patient died within 4 months of presentation.
